I TBENCH-SANDAL.

' To all whom it may concern:

" Be it known that I, Cinemas 0. Ron, a

-' citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Trench-Sandals,;of which the following is a 'specification.

This invention relates. to sandals to be worn with boots or shoes for trench work in warfare and also in peaceful pursuits when walking over rough, icy and uneven slippery ground.

One of-the objects .of the invention consists 1n the provision of a sandal to be worn with boots and shoes, which will stand far greater and. harder usage than leather;

which will give the wearer a firmer footing underall kinds of ground and weather conditions; also preventing the wearers feet from becoming sore by reason of the soles of the boots and shoes wearing thin, thereby promoting and maintaining a healthier coir dition of the feet, and also retarding fa tigue of the wearers, by i'naintaining a'betterlxeiuipoise of the body.

urther object of theinvention consists in the provision of a sandal wherein worn down spikes in the soles can be easily and readily replaced, thereby prolonging the life and utility of the sandal with a corresponding reduction in costlof replacement and maintenance. I I

I accomplishthe abov'eobjects of the invention, and such others as may appear from a I perusal of the specification and I claims, by means of the construction illustrated in the accompanying drawing, formmg a part hereof, 1n wh1ch I Flgure 1' 1s a side elevation of my 1mproved sandal, showing the manner in which the same is held in position on the wearers I foot. Fig. 2 is an underside plan view of the sandal. Fig. 3 is a top or planview of the sandal. Fig. {lis a fragmentary detail'cross sectional view, on an enlarged scale, showing one of the locking devices, on a line 4 4: in Fig. 3. Fig. 5 is a fragmentary detail .lon itudinal sectional view, on an enlarged sca e,showing more clearly the construction and arrangement ofthe parts. Fig. 6 is a fragmentary detail perspective view, showing the manner in which the counter of. the sandal isattached to'the sole-plate. Fig.6?

is a perspective view of one of the spikes, (lb.

the remaining parts being omitted.

Referringto the drawings, the sole and. heel of the'sandal are preferably composed of thin sheet steel plates to sustain the rough usage to which they are subjected.

The sole of the sandalis composed of at least three sections 10, .11 and 12 which are hingedly secured together by means of the hinge-connections 14 and 15'. The hinge connections 14' and. 15 extend transversely of the sandaland are locatedimmediately beneath. the ball of the foot where the greatest amountof bending occurs, and wherethe greatest amount of elasticity is required.

The free end of section 10 is bent downward-1y at right angles to provide an extension 16 which is slightly less theheight" of the heel on the shoe, thereby providing some latitude for the wearing down of the heel.

Section '17 which forms the heel of the sandal is bent upwardly at one end to form a member 18 which member rests againstextension '16, and member 18 is bent at right angles to form a member 20 which rests against the outer surface of section 10 ofthe 0 sole, and members 16 and 18, and, also, members 10 and-'20 are rigidlyffsecured together by means of suitable rivets, or byspot-weld ing. This overlapping of sections 10 and 17 reinforces the sandal at its weakest point'--- where the sole and heel sections join. Section 12 of the sole is provided with a shoetip 22 to form a pocket for the toe"ofmthe boot or shoe, and the heel section 17 is provided with a counter 21 for holding the boot '0 I, or shoe in position in thesandal. Counter 21 is provided opposite sides with a slot 21 adapted to receive a strap 23, the latter passing over the instep of the foot andserves a to hold the sandal in operative'position, on-

thef boot or shoe. In addition to strap 2 provide a strap 24 whichpasses over the hall of the foot and engagesthe ears26 formed 1 I integrally with section 11,'and also with-the ears-27 formedint'eg'rallywith section 12v of 10. the sole. Heel-section 17, sole sections 10% 1'1 and 12 are provided with a plurality o apertures-30, and 'through these apertures I pass suitable tempered steel spikes 31.

are provided with thin flat headsjlqfi, 32 so as to extend but a short distance above the surface of sections "10,. 11,..12-53gnd Spikes 31 are easily removed- Spikes 31 30 when worn down to where their destroyed and may be easily replaced by the introduction of new spikes 31 into apertures 30, thereby making the sandals as effective as when new, Spikes 31 are prevented from backing out or being displaced from ,aper" tures 30 bymeansof suitable plates which rest tightly upon the flat heads of said spikes. To render the plates to be more easil *removed'and inserted they are-preferab y divided along their longitudinal centers into two members, in which the sections 35 and 36 are arranged within the heel portion of the sandal; members 37 and 38 being arranged in section 10 of the sole, and" members 39 and-40 in section 12 of the sole.

3' Section 11 is provided with'a single member 41, the latter being narrow and easily sprung upward in the. center to remove it, so that this member may be made of a single piece T of material. The outer edges of heel-membore and Bit are held down into contact with theheads of the underlying spikes 31 2 by means of the marginal ears 45 which are 25 formed out of the adjacent edges of, heel sections 17, these ears being bent down wardly to form hooks under which the edges of members 35 and 36 are inserted. The

outer edges of members 37 38, 39, ,40 and 41 i 80 are held down by the hooks 44 which .are

' formed by lip-turning the edges of said.

' plates. The meeting edges of members 35, 36, 37, 38, 39 and .40have cooperating depressions 46, and these meeting edges in the 35 bottoms of these depressions are provided "with notches to form elongated slots 47.

' surface with a kerf 51, adaptedqto receive the end of'a screw-driver, or similar tool,

for'rotating pins 48 so as to move heads 50 50 to stand either transversely across the edges to lock the plates or parallel with slots 47 to permit the removal of the plates.

By means of the herein described construction, the plates may be easily unlocked and taken out for the removal and replacementof spikes 31, when the latter have become sufficiently worn to be unfit for further ser- T106.

, Having thus'fully described my said in- '00,!" of fllll pltfllt may be obtained for live cents each, by addressing the Commissioner of latenta, A

"Patent, is

ffvention, what I desire to secreby Letters 1'. A sandal of the herein de colilprising a,sole-member composed of a pluralityot hingedIy connected sections containing a plurality of perforations, spikes passing through said perforations, means formed along the edges of said sole-member for securing the marginal edges of a spikeretaining means, a spike-retaining means adapted to be inserted under the preceding means and resting upon the upper ends of v the spikes for holding the latter in operative position, and means for locking said spike-retaining means in operative position.

2. A sandal of the herein described class comprising a sole-member composed of a plurality of hingedly connected sections containing .a plurality of perforations, a heel-member attached to the adjacent solesection and provided with perforations, spikes passing through said erforations, retaining-means for holding the spikes in operative position, and means for locking said retaining-means in operative position;

3. A sandal of the herein described class comprising 'a sole-member composed of a pluralityof hingedly connected section's con-v taining a plurality of perforations, a heelmember provided with perforations attached to the adjacent sole-sectiomspikes passing through said perforations, spike-retaining means for holding the spikes in operative position, means arranged along the outer edges of the heel and sole members for securing the marginal edges of the spike-retainingmeansin operative position, a spikeretaining means,and means for locking the spike-retaining means inoperative position. 4. A sandal of the herelfi described class comprisingv a sole-member composed of a plurality of hingedly connected sections containing a, plurality of perforations, spikes passing through said perforations, spike-retaining means for holding said spikes in operative position and provided with slots, pins arranged in said sole-member and extending through said slots, transverse heads on said pins for locking the spike-retaining means when the heads stand transversely of said slots, and, means for securing the .marginal edges off said spike-retaining means in operative position. y

In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana,
